Abstract: A half mirror includes a circularly polarized light reflecting layer including a cholesteric liquid crystal layer, a barrier layer, a bonding layer, and a front panel. The barrier layer, which is, for example, a layer formed by curing a composition containing a urethane (meth)acrylate monomer, is disposed between the bonding layer and the circularly polarized light reflecting layer.
